Abstract

The main working body of technological equipment of screw rotor technological systems are screw rotors which present spatial objects with an original geometrical shape of working body perimeter in which component parts and granules of the processing environment carry out simultaneously continuous rotation around the axis of working body and progressive motion, constantly moving along a horizontal axis of working body rotation. This article gives a classification of perimeter forms of working bodies, such as screw rotors, which let to expand technological possibilities of technological equipment and to provide the increase of effectiveness of the production process by means of increase of its amplitude-frequency characteristics. The peculiarity of working bodies in the form of screw rotors is the fact that internal cavity of a rotor has a wavy shape, formed by the sides of a semicircular form. The paper covers on a construction and the principle of operation of machine-tools on the basis of working bodies in the form of screw rotors with a shaped surface on perimeter. The suggested design solutions of processing equipment allow creating highly effective machine-tools for the finishing and strengthening processing.
